Hello,
Sorry for spamming, I found a bug in the class I sent you this morning: so
just to see how tedious it is to point to the same Date with separate
tc:date and tc:time tags, if every tag was just updating the fields he
shows, we could point to the same field without ths linking cables:
*public* Date getWorkStartTime() {
*return* getCurrentWorkTask().getWorkStart();
}
*public* Date getWorkStartDate() {
Date start = getCurrentWorkTask().getWorkStart();
*if*( start == *null* || CalendarUtil.*equalsDate*( start,
1970, 0, 1 ) )
*return* *null*;
*return* start;
}
*public* *void* setWorkStartDate(Date workStart) {
getCurrentWorkTask().setWorkStart( CalendarUtil.*setDate*(
workStart, getWorkStart() ) );
}
*public* String toString() {
*return* getCurrentWorkTask().toString();
}
To remind what I would like to have here's what I expected from these
components:
<tx:date
id ="workStartDate"
value ="#{intervention.*workStart*}"
label ="#{i18n.workStartDate}" >
< f:convertDateTime pattern ="dd.MM.yyyy" />
</ tx:date>
< tc:time
id ="workStart"
value= "#{intervention.*workStart*}" />
in that case all the code above is simplified in a pojo manner.
Regards,
Zied
